You do work on something when you lift it against gravity. How does this work relate to gravitational potential energy? If the lifted object is released, what becomes of this energy? Be sure to define all terms that you use.

Question

agent0smith · Answer

Lifting an object increases it's gravitational PE. If you release the object, that PE will be transformed into KE as it falls toward earth.

anonymous · Answer

the potential energy is converted into kinetic enery..

anonymous · Answer

so what does it mean  when it says to define all terms you use

agent0smith · Answer

Just define things like gravitational PE, and KE. 

Grav PE = an objects potential energy due to gravity and it's height.

Kinetic energy = an objects energy due to motion.

Lifting an object increases it's gravitational PE. If you release the object, that PE will be transformed into KE as it falls toward earth.  Grav PE = an objects potential energy due to gravity and it's height.

Kinetic energy = an objects energy due to motion. so this would be my answer

agent0smith · Answer

Well yes something like that, but you should write PE and KE as potential energy and kinetic energy.

anonymous · Answer

u mean like right what they mean

agent0smith · Answer

No i mean... write potential energy instead of PE :)

ok thank you
